What should I watch for while using this medicine?

Visit your doctor or health care professional for regular checks on your progress. It can take several days before you feel the full effect of this medicine. If you have been taking this medicine regularly for some time, do not stop taking it at once. You must  reduce the dose gradually or you may get severe side effects. Ask your doctor or health care professional for advice. Even after you stop taking this medicine it can still affect your body for several days.

Patients and their families should watch out for worsening depression or thoughts of suicide. Also watch out for sudden or severe changes in feelings such as feeling anxious, agitated, panicky, irritable, hostile, aggressive, impulsive, severely restless, overly excited and hyperactive, or not being able to sleep. If this happens, especially at the beginning of antidepressant treatment or after a change in dose, call your health care professional.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may increase dizziness and drowsiness. Avoid alcoholic drinks.

Do not treat yourself for coughs, colds, or allergies without asking your doctor or health care professional for advice. Some ingredients can increase possible side effects.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.

Protein binding

Equilibrium dialysis indicate a mean protein binding of 75.5% for doxepin and 76.0% for desmethyldoxepin [2].


Oral LD50 values in mouse and rat are 180 mg/kg and 147 mg/kg, respectively [MSDS]. Cardiac dysrhythmias, severe hypotension, convulsions, and CNS depression, including coma. Changes in the electrocardiogram, particularly in QRS axis or width, are clinically significant indicators of tricyclic antidepressant toxicity.

No evidence of carcinogenic potential was observed in mice studies. Doxepin was negative in in vitro (bacterial reverse mutation, chromosomal aberration in human lymphocytes) and in vivo (rat micronucleus) assays, indicating it is unlikely to be mutagenic compound [7]. The effects of doxepin on fertility were investigated in male and female rats. Adverse effects on fertility (increased copulatory interval and decreased corpora lutea, implantation, viable embryos and litter size) and sperm parameters (increased percentages of abnormal sperm and decreased sperm motility) were observed [7]. However the AUC for doxepin and nordoxepin at the no-effect dose for adverse effects on reproductive performance and fertility in rats (10 mg/kg/day) are less than those in humans at the maximum recommended human dose of 6 mg/day [7].

Half life

Half life of doxepin ranges from 6 to 24.5 hours. The mean distribution half-life of doxepin was 2.0 hrs and the mean elimination half-life ranges from 15.3 to 17.9 hrs [2, 7]. The apparent terminal half-life of desmethyldoxepin was 31 hours [7].
